Create votive holders from your black and white pictures. I think this would be great for other glasses too... pictures of the couple throughout their courtship would make a great wedding gift as a lovely set of bar glasses.
old family photos into mementos. Very cute idea. This would b very cool on a family "tree" as ornaments! I would not use original photos though, and instead scan them into the computer and print them out. And I would perhaps use those glass rocks with flat bottoms?
